Review on 🔐 CATALYST 200 Pocket U-Lock - Silver: Superior Security for Bikes by Brad Jeffress

The lock is nice and small, not too big but not too small either. I had no problem mounting my bike on a bike rack on campus. However, after a few weeks the locking mechanism started to fail. The lock refused to open or close with any key and I wasted time locking and unlocking my bike. You really have to be patient. This is a great budget lock but if you have the money to upgrade to a higher quality lock I would recommend a higher quality lock.
